GEQKETRICALLY-PROGRESSIVE CONTROL SYSTEM.

Specification of Letters Patent.

Application filed March 24, 1914. Serial No. 826,862.

To all whom it may concern:

Be it known that we, CHARLEs J. HEN- scHEL, a citizen of the United States,-residing at Bloomfield, in the county of Essex and State of- New Jersey, and CHARLES MEs- SICK, a citizen of the United States, residing at Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Geometrically-Progressive Control Systems, of which the following is a specification.

Our invention relates to control systems of the type sometimes designated as remote control systems, and used for various purposes, such as signaling, or broadly speaking, for'causing a movable member of any kind to execute a movement analogous to a I 7 corresponding movement made by some other movable member at 20.

a pointvlocated reniotely therefroin- Insuch systems there is usually a driving member, located at a point which maybe'designated as a transmitting station, and a driven member located at another-point remote from the transmitting station, and which may be considered as a receiving station. The driven member, located at thereceiving-station, executes a movement simulating, or at least in some manner representing, a more or less analogous movement made by the driving member at the transmitting station-the movements of this driving member being oftentimes, though not necessarily, made by B our invention from the transmitting station to the hand, or'at least; controllable at the will of an'operator located at the transmitting station.

the type above mentioned, and provide in such system a number of individual controlling members, paths of communication each extending receivand under control of the driving station,

at the transmitting station for ing member the purpose The several quantitatively the driven member'at the remember at the receiving station under control of any or all of the individual controlwe employ a system of associated with different of actuating the driven mem ber at the receiving station. 4 controlling members are arranged to actuate Patented May 18, 1915.

which, at any particular-moment, are selectively thrown into action. I

y arranging our system as just stated, a large number of separate and distinguishable movements may be executed by the driven member at the receiving station, for a given number of individual controlling members and separate paths of communication.. For instance, with each additional controlling member used in the relation stated the aggregate number of separate movements, capable of execution by the driven member at the receiving station, may be"doubled'.. Therefore the number of separate indications possible of execution at the receiving station may thus be in geometrical ratio to. the number of separate controlling members and paths of communication employed.

ile our system admits of a great variety of uses, and may befemployed in many distinct relations,-we will for the sake of conciseness show it as embodied in a single representative ITIBChfl-IIISI'II, namely, a signaling system adapted for use, for instance, as

a ships telegraph. In this particular form of our device the driven member atthe receiving station is an indicator capable of measuring quantitatively; the drlvlng member, located at the transmitting station, s a hand operated electric switch; the 1nd1- vidual controlling devices for aflecting the indicator are a number of solenoids each provided with 'a movable core,',the stroke of each core being different, in geometrical ra-.

tlon, and in which like letters indicate like parts, the figure representing the ships telegraph complete;

A switch board 8, located at the transof display'marks 0, 1, 2, 3, 4, 6, 7, such display marks in this instance being eight in number. r

A contact ring 9 is mounted uponthe switch board 8, and adjacent this ring is a revoluble switch arm 10, held in position by a pivot pin 11, and provided with ahan; dle 12 whereby it may be turned or swung to different angles. The switch arm 10 car ries a contact bar 13 and strip '14 of insulating material, whereby the arm is insulated, The switch board 8 is provided with 'a number of stationary contact members 15, 16, 17 each of which is connected with a wire 18extending to the receiving station shown in the upper portion of the figure. Another stationary contact member 19 is connected with this wire by ,a short wire 20. A number of other stationary con tact members 21, 22, 23 are connected with a wire 24. A stationary contact member 25 is connected with this wire 24 by a wire 26.

Other stationary contact members 27, 28, 29, 30 are connected witha wire '31, leading also to the receiving station.

A wire 32 is connected with the ring 9, and with a source of electricity 33, which in this instance is a-dynamo. A wire 34 leads from this dynamo to the receiving station.

A board 35, locatedat the receiving Sta-- tion, supports the various parts employed at said station. Mounted upon this board are a number of solenoids 36, 37, 38- provided with movable cores 39, 40, 41. The solenoids in question are connected with'the wires 18 24, 31. They are also connected, by wires 42,43 and 44, with the wire 34, which thus acts as a. return wire for all of the solenoids.

Secured to a fixed pin 46, carried by the board 35, is a flexible connection 47,'preferably a chain. This flexible connection also engages a pulley 48 for the purpose of actuating the latter positively. A dial 49, carried by the board 35, isprovided with display legends, in this instanceeight in number, namely, 0, 1, 2, 3, 4, 5, 6, 7, corresponding to the display legends carried bythe board 8. A pointer 50 is mounted rigidly upon the pulley 48, and normally rests against ,a' stopfpin 51, and in such position as to designate the legend 0. The pulley 48 is mounted to turn upon a pin52.

Associated with: the, solenoids 36, 37, 38, are sheave wheels 53, 54, 55, which are re spectively engaged by the flexible connection 47. Each sheave wheel is journaled in a bearing 56 providedwith a cross bar 57, each core 39, 40, 41, carrying one such bearing, sheave wheel and cross bar. Adja-.

limiting travel of the adjacent core in one direction, The travel of each core in the opposite direction is limited by the top por- The sol tion of the solenoid against which the cross bar lodges as the core is drawn downwardly to the limit of its stroke.

Two other pulleys 59, located over the solenoids, are engaged b nection' 47. This flexiblm connection, in engaging theevarious pulleys 48, 59, 53, 54,

and 55, is woundsinuously' back and forth.

A weight 60, carried by the flexible connection 47, hangs below the pulley 48. This 1 weight maintains the flexible connection 47 taut at all times, and normally supports the various cores 39, 40, 41in their respective uppermost positions, The relative degrees of play allowed the cores 39, 40, 41'respec- ,tively, is such 1 that the core 40 is free to move twice-as far as the core 39', and the core 41 isada'pted to travel double the distance the core .40 is capable of traveling.

While in this instance'weshow .only three solenoids, any larger number may be employed. Each successive solenoid added should have its core so arranged as to travel double the maximum distance. traveled by the flexible contravel four inches, and any successive cores added should travel eight inches, sixteen inches, thirty-two .inches, etc.each successive core traveling double the distance of the one preceding it. I

The parts are so proportioned and arranged that when the core 39 is drawn downwardly by the solenoid 36, thepointer 50 travels a distance equal to the distance between any two successive legends on the .dial 49. Each time the core 40 is drawn downwardly by the solenoid 37, the pointer 50 travels a distance representing two su'ccessive legends, carried by the dial 49. A v t down-stroke of the core 41 causes the pointer 50 to move a distance represented by four successive legends carried by the dial. in question. I

either one at 'a time, or in groups of two or three at a time, and when energized in groups, their effect upon the flexible "connection 47 and pulley- 48 is cumulative, so that the pointer 50 registers an indication commensurate with the aggregate degreeof travel of all of the cores afl'ected [at aparticular moment. Therefore, by separately energizing each solenoid, and-bv energizing diflerently-selected groups of the solenoids, the pointer 50 can be caused to register a large number of indications. Y i The precise number of indications which may be registered by a given nnmber of solenoids increases in geometrical progres sionto the number of solenoids, as above explained. With a single solenoid, two indications can be made, one of theseor" course being the normal or so-called zero position.

enqids 36, 37, 38 may be energized With two solenoids four indications can be made, including said zero position. With three solenoids, the number of indications increases to eight. With four solenoids, the

number of indications possible would be' successive solenoid added thus sixteeneach doubling the number of'indications' which the core 39 could be made without it.

The sum of the traveled by the cores 39, 40, 41, or any of them, is equal to one. half of-the rotary travel of the pulley 48. This is because the leverage between the flexible connection 47 and the various pulleys is so apportioned that the rotary travel of the pulley 48 is erator at the receiving station by causing the pointer to moveto the display legend The transmitting operator grasps the handle 12 and turns the arm 10-into such position that the contact bar 13 engages the stationary contact member 15. This completes-a circuit as. follows: Source of electricity 33, wire 32, contact ring'9, contact bar 13, stationary contact member 15, wire 18, solenoid'36, wires 42 and-34, back to source of electricity 33. This circuit energizes the solenoid 36 and causes it to draw downward to the limit of its travel. The pointer 50 is thus moved to. the

angular extent necessary to shift it tothe display legend 1. Suppose, next, that the transmitting operator shifts the switch arm 10 to, the display legend 2 board 8, so that the contact the stationary contact member 21. The following circuit is thus complete'd; Source of carried by the electricity 33, wire 32, contact ring 9, contact member 13, stationary contact'member' 21, wire 24, solenoid 37, wires 43 and 34, back to source of electricity 33.- This energizes the solenoid 37, and thepointer 50 moves around to the legend'2 on the dial 49. Assume, next, that the transmitting operator moves the switch arm 10 around to the legend 3 of the dial 8. The contact bar 13 now engages two stationary contact members16 and 22. A circuit is thus completed as ,follows I contact ring 9, contact bar 13, stationary contact member 16, wire 18, solenoid 36,

The solenoid 38, being draws the core 41 down: to 5 the lower limit of its travel, so

18, solenoid 36, and

contact ring 9, contact stationary contact member 17, wire wires 42 and 34, back 1054 to source of electricity 33. Another circuit is also completed as tricity 33, wire 32, bar 13, stationary c 31, solenoid 38, and

The switch next be movedfsay, to the legend 6 carried by the board 8. This brings the contact bar 13' into engagement with the two conta ct.members 23 and 29.

A, circuit thus completed'may be traced as follows contact ring source of electricity 33, wire 32,

9, contact bar 13, contact mem- 2 ber 23, wire 24, solenoid 37, and wires 43 1 and 34 back to source of electricity 33.

Another circuit may also be. traced as follows: source of electricity 33,- wire 32, con

tact ring 9, contact tact member 29, wi

bar 13, stationary conre 31, solenoid 38, and

wires 4:4: and 34, back to source of electricity 33. As the two circuits just traced include 41 are drawn downwardly, and the pointer 50 moves to an extent representing the ag gregate travel of these two cores. pointer 50, therefore, moves to the legend 6, upon the dial 419. Lastly, suppose that the switch arm 10 is moved around to the legend 7 carried by the board 8. The contact bar 13 now rests upon three contact members 19, and 30. A. circuit thus completed is as follows: source of electricity 33, wire 32, contact ring 9, contact bar 13, stationary contact member 19, wire 20, wire 18, solenoid 36, wires 42 and 34, back to source out electricity 33. -Another circuit completed 'may thus be traced as follows: source of electricity 33, wire 32, contact ring 9, contact bar 13, stationary contact member 25,

wires 26, 2d, solenoid 37, wires 43 and 34L,

back to source of electricity 33. A third circuit, also now completed, may be traced as follows: source of electricity 33, wire 32, contact ring 9, contact bar 13, stationary contact member 30, wire 31, solenoid 38, and wires 4a and 34:, back to source of electricity '33.

As the three circuits just-traced include.

I the three solenoids 36, 37, 38, these solenoids and stops at the legend 7.

are energized, the'cores 39, 40 and 41 are drawn downwardy, and the pointer. 50 moves to an extent commensurate with the aggregate travel ofnall three of the cores,

Whenever, after making any indication stored to its normal position, or eve sufi'iciently in either direction to disconnect the contact bar 13 from the stationary contact member or members engaged by said contact bar, the weight 60, by turning the pulley 48, causes the pointer 50 to move into its normal position, and to indicate the legend 0. ln fdoing this the weight also restores all the movable parts at the receiv-- ing station to their respective normal positions indicated in the drawing.
